Google SketchU People Library6.0

Traditional drawing is about translating what you see onto a flat piece of paper: going from 3D to 2D, which is hard to do for most people. Do you need to know how to draw to use SketchUp? In SketchUp, you’re always in 3D, so no translation is involved — you just build, and SketchUp takes care of stuff like perspective and shading for you.
